MIB 303 Solids-retaining Centrifugal Separator Application The MIB 303 separation system is designed for centrifugal separation of sludge and water from mineral oil. The separator is designed for oils with a maximum density of 920 kg/m3 at 15°C. The maximum separation temperature for gas oil and marine diesel oil is +40°C, and for lubricating oil +70°C, since this is the max. separation temperature for the separator. Mineral Oil The MIB 303 separator in a cleaning system for distillate and marine diesel oil should be operated as a purifier. For cleaning of lubricating oil, MIB 303 purifier or clarifier can be used. Concept The MIB 303 separator features a new design concept for solid-bowl separators. Advanced manufacturing, design and drive technologies have contributed to a separator more compact and lightweight than conventional solid-bowl models. Features • No lock ring. Requires only small mechanical force on opening/assembling of the bowl. • New design allows the bowl wall to be taken out and cleaned with the disc stack still in place. • New lightweight materials in bowl and discs. • Direct drive with motor speed controlled by a frequency converter eliminates gears or belts. • Requires no lubrication. • The cleaned oil is discharged under pressure, due to the built-in paring disc pump. • Frequency converter with built-in voltage protector.

Benefits • Easy to install, operate and maintain. No special training required. • Small dimensions allow installation in narrow spaces. • Removal of solid impurities extends intervals between filter replacements, which saves filter costs and reduces filter disposal handling. Oil inlet Clean oil outlet • Removal of water from mineral oil improves the reliability of the oil system. It also reduces the risk of bacterial growth in tanks that could clog the filters. Bowl Solid space • Electronics protected from voltage variations. Throughput capacity The MIB 303 separator has a throughput...

Purifier operation Separation takes place in the rotating solid-wall bowl. The uncleaned oil is fed into the bowl where the centrifugal force makes water and solid particles move out towards the periphery of the bowl, while the clean oil flows inwards. Clarifier operation In clarifier mode the oil normally does not contain any free water. The separation principle is similar to that of the purifier, although there is no water seal and no water outlet in the bowl and the water handling capacity is limited. To establish a water seal during start-up of the separator, water is added to the bowl...
